Plant Structure and Function

What is a small opening in leaves that allows gases to pass in and out of a plant?

• cell plate
• petiole
• stomata
• trichome

transport food and water throughout the plant

• ground tissues
• meristematic tissues
• vascular tissues

what's the purpose of the phloem?

• to bring water through the stem
  
• to bring food through the stem
• Captures the sunlight
• makes the plant green

what's the purpose of the xylem?

• to bring the food through the stem
• to capture sunlight
• produce pollen
• to bring the water through the stem

The two structures that limit transpiration  are known as

• Guard cells and xylem
• Stomata and guard cells
• xylem and phloem
• stomata and phloem

Leaves are part of a plant’s shoot system. The xylem tissue in leaves transports

• the bacteria needed for nitrogen fixation in root nodules.

• the wax required to coat the surface of actively growing tissue.

• the water and minerals that are absorbed by the roots.

• the oxygen that regulates the rate of carbohydrate production.

The anther and filament make up the stamen. What is their primary function

• Pollen production

• Egg development

• Pollen transfer

The flower petal is responsible for

• Pollen production

• Attracting pollinators

• Pollen transfer

The stigma, style, and ovary make up the pistil. What is the primary function of the pistil?

• Pollen production

• Egg development

• Pollen transfer

Which part produces sperm enclosed in pollen?

• A
• B
• C
• E
